That looks slow.  On an Athlon 1 GHz, our simulators
(ocaml and C) need less than 3 seconds for 100K cycles
without traces and less than 5 minutes to generate the
trace for the contest sample(10K cycles).

BTW ocaml is very very fast, faster than C depending on
the OS/machine used ; congrats to my teammate :)
